Description:

While the traditional way to start seeds is to use soil, there are some good reasons to use sponges for seed growing: You don’t need messy soil. You can watch the seeds grow and roots develop. Sponge seed germination happens rapidly. It’s easy to sprout a lot of seeds in a small space. The sponges can be reused if seeds turn out to be unviable. It makes a great experiment for children.

Great plant choices for seed rowing on sponges: Lettuce, watercress, carrots, mustard, radish, herbs, tomatoes.
